Offshore wind power based hydrogen production and organic liquid hydrogen storage energy-storing system and method

Abstract

The invention discloses an offshore wind power based hydrogen production and organic liquid hydrogen storage energy-storing system and method. The output end of an offshore wind power generator is connected with the input end of a power divider, two output ends of the power divider are connected with the input end of an AC / DC rectifier and the micro grid respectively, the output end of the AC / DC rectifier is connected with a power interface of a seawater electrolyzing hydrogen production device, a hydrogen outlet of the seawater electrolyzing hydrogen production device is communicated with aninlet of a liquid hydrogenation device, an outlet of the liquid state hydrogenation device is communicated with an inlet of a liquid hydrogen storage tank, an outlet of the liquid hydrogen storage tank is communicated with an inlet of a liquid dehydrogenation device, a hydrogen outlet of the liquid dehydrogenation device is communicated with a hydrogen inlet of a fuel cell power generator, and theoutput end of the fuel cell power generator is elected with the micro grid via a AC / AC inverter. The system and method can be used to solve the problems of energy supply in remote islands as well asintermittence and fluctuation of wind energy.

Description

technical field [0001] The invention belongs to the field of hydrogen energy, and relates to an energy storage system and method based on offshore wind power hydrogen production and organic liquid hydrogen storage. Background technique [0002] There are many coastal islands in my country. Due to the limited load and long transmission distance, the laying of submarine cables requires a higher technical and economic cost. Therefore, remote islands generally lack power supply. On the islands, wind energy resources are abundant, and offshore wind power generation has become an ideal choice for island energy supply. Wind energy is an inexhaustible and non-polluting energy source, but its intermittent and fluctuating characteristics cause wind power to also present a random and fluctuating state. Energy storage technology has the characteristics of dynamically absorbing energy and releasing it in a timely manner, which can effectively make up for the intermittent and volatile sh...
